R parity can spontaneously break
J C Romao, C A Santos, J W F Valle
Abstract
We refute the claims made by Chaichian and Smilga in a recent paper in Phys Rev Letters on the impossibility of spontaneous R Parity breaking. Apart from explaining their error we summarize the results of a more detailed work that demonstrates explicitly that R parity can break spontaneously at a scale anywhere in the range 10 GeV to 1 Tev in a simple extension of the minimal SUSY standard model proposed previously.
